SFA
Sensor Fullscale Adjust
(Factory characteristic – fullscale value)
Range:
0...1,599999e6
Factory setting:
adjusted to nominal load of transducer
Response time:
<15ms...4.2s
Parameters:
1 (0)
Password protection:
yes
Data protect.:
with input
Input:
SFA;
(Response time: <4,2s)
Effect:
Using this command, the transducer electronic system measures an input signal
between ±2.5mV/V, stores the measured value as the fullscale value of the
factory characteristic and calculates the new characteristic together with the
previously entered value for
SZA.
Input:
SFA <fullscale value>;
(Response time: <15ms)
Effect:
Instead of causing the AED to measure the applied signal, here the value is
entered directly as the fullscale value of the factory characteristic, stored and
used together with the previously entered value for
SZA.
Query:
SFA?;
(Response time <15ms)
Effect:
The value used in the AED for calculating the factory characteristic for the zero
point is output in ±7 digits (e.g. -0915345CRLF).
Important Note
Entry the command SZA and SFA ore execute. The data will be calculated if both parameters were given in
pairs ore been measured.
Procedure for
entering the factory characteristic
:
1.
Enter password by means of command SPW
2.
Switch off the scaling withNOV 0; output (scaling off)
3.
Deactivate user characteristic by means of
LDW0;
and
LWT1000000;
4. Adjust
the
ASF
filter such that a maximally quiescent display is effected
5.
Transducer (not scale) without load, wait until standstill
6.
Determine measured value with
MSV?;
, note value1 for
SZA
7.
Load transducer (not scale) with nominal load, wait until standstill
8.
Determine measured value with
MSV?;
, note value2 for
SFA
9.
Enter new characteristic with : SZA value1; subsequently SFA value2
10. Redetermine the user characteristic LDW/LWT
The points 3...8 are not applicable if the factory characteristic is entered anew using already known parameters.
